- Multiple parameters per LFO, including variability.

- Wide rate range, from 1/128 to 130442 beats.
- 9 factory and 16 user shapes.

### 5/5 — 🤩 Oh yes

*2026-06-23*

Wo langsam noch zu schnell ist! Diese LFO können sich wirklich Zeit lassen bei Bedarf. Super, dass es diese AU gibt…

### 5/5 — Love and a request

*2025-05-21*

I absolutely love this app. Use it on every session. One feature wish to have is to be able to draw custom shapes by bar count. That would effectively give us automation in AUM. You can currently draw shapes but their points on the LFO are more approximations. Even if it were just a bar count label that updates visually as you move a custom point along the LFO timeline. 

But still, this app is a must-buy for AUM users.

### 5/5 — There are few things better

*2025-02-07*

LFO heaven. Easy to use interface. Super connectivity. And almost more LFOs than you’ll need in any one instance, 16 of them. If you need more add another.

### 5/5 — Way better than

*2024-11-28*

Your current LFO.  Worth the price of admission

### 2/5 — Doesn’t work on iPhone

*2024-03-19*

Doesnt run in Aum or AudioBus on iPhone. It is paused indefinitely, the LFO should be playing. Spent a couple hours trying to get it to work in Aum not realizing that its just not compatible on iPhone. Really love the idea of plug-in was really excited to use it, please let me know if you get this fixed!

### 3/5 — Great but …

*2023-12-08*

… when trying to edit the curves the handles quickly become unresponsive.

### 4/5 — Nice app but

*2023-11-29*

It won’t let me edit points on the custom curves

### 5/5 — Amazing lfo app

*2023-07-16*

It’s both amazing to use for seasoned musicians and also educational if you still have things to learn

### 5/5 — My Go-To LFO App

*2023-05-25*

I have several LFO apps, modulation is very powerful in music production. This is easy to use, clean gui, lightweight, customizable, versatile, and has everything you need in a LFO app. Since it’s release every time I want to modulate something I almost always turn to mLFO. It has 16 LFO’s in one, so I only need one instance per session. Lots of options for waveforms, even custom waveforms. They just added an ADSR for your waveform curves and there is such a wide range of Rates that you can modulate something as slow or as fast as you could possibly need. Phenomenal app at a great value. Best LFO on iOS!
